I would tick them and keep them if I were you. These allow access to third party software:


The "Third-Party Software" tab is where you will be able to add the Canonical Partner Repositories. You will see two Canonical Partner repositories listed - one for applications and another for source code (src). The partner repositories offer access to proprietary and closed-source software and are not enabled by default.

ah i see, thanks man
but the reason i ask is beacause when i hit reload i get this error

W: GPG error: http://ppa.launchpad.net jaunty Release: The following signatures couldn't be verified because the public key is not available: NO_PUBKEY 5A9BF3BB4E5E17B5

OK, run this command in a terminal:

sudo apt-key adv --recv-keys --keyserver keyserver.ubuntu.com 5A9BF3BB4E5E17B5

This will get you the key.
